Of all Gamma Ray's albums, their first three have always had that Helloween feel to them. As band leader Kai Hansen had written a fair bit for Helloween, this shouldn't quite come off as a surprise. But of each of Gamma Ray's first three albums the Helloween influence is most noticeable here, on Insanity And Genius.

This is the only GR album I've heard before they had a really successful career period with Land of the Free, etc. As it is, this is still a pretty solid, powerful metal album with a couple of woefully cheesy anthems ("Gamma Ray" and the title track to be specific), but generally I found it an enjoyable record to listen to on a lazy Sunday. I would say the first half of the album (songs 1-5) is stronger in terms of songwriting and instrumental performance, but the album closer is pretty good stuff too.
